Abstract: The two-tier Lowry model brings dynamic simulations of population and employment directly into the planning process. By linking regional modelling with neighbourhood design, the framework enables planners to explore how alternative planning scenarios may evolve over time. The upper tier captures regional flows of people, jobs, and services, while the lower tier allocates these to fine-grain zones such as neighbourhoods or parcels. Implemented in CityEngine, the approach allows interactive visualisation and evaluation of multi-scale scenarios. A case study in South Yorkshire (UK) illustrates how regional forecasts can be translated into local design responses, connecting quantitative modelling with 3D spatial planning.
